Answer to Question 1

ANS: D
The object of delayed-type hypersensitivity is to rid the body of bacteria that replicate within macrophages. The macrophage activates the CD4 cell, which in turn activates the macrophage. The other cells listed are not a part of this response.

Answer to Question 2

ANS: C
When antigens bind to antibodies on mast cells and basophils, chemical mediators of hypersensitivity reactions are released. Although hypersensitivity is an acquired response, mast cells and basophils do not play a role in other acquired responses. An autoimmune response occurs when the immune system fails to discriminate between self and nonself. Transplant rejection occurs when the MHC molecules of the donor are different from those of the patient.
